Clean Marine

Cobourg Marina and Harbour is proud to be striving towards Eco-Excellence in pollution reduction. We received 5 Green Leaf Anchors in our first year!

In October 2020, Cobourg joined the Great Lakes Plastic Cleanup, with cleanup and capture technology installed thanks to the support of Ontario's Ministry of the Environment, Conservation and Parks. 

We also found intact items in the bins - including cigar tips, straws, masks, coffee cup lids and bottle caps!
